2024-05-05reverse: use incrementing inode number for gocryptfs.longname.*.name filesJakob Unterwurzacher
ed0a12b7337c2d88c027329f64e73070da17d5b3 already fixed the kernel side, now we also want the .name files to NOT appear hardlinked when just looking at the inode number. Relates-to: https://github.com/rfjakob/gocryptfs/issues/802
2024-05-01reverse: use unique generation number for all nodesJakob Unterwurzacher
We used to present gocryptfs.longname.*.name files for hardlinked files as hardlinked to the kernel (same Node ID) which is wrong. Fix this by using a unique generation number for all nodes, which also fixes possible issues with inode reuse. Basically what 1bc1db620b061aabf59469a5eb4fb60e3e1701a3 did for forward mode with -sharedstorage. Fixes https://github.com/rfjakob/gocryptfs/issues/802

2022-04-02Fix reverse gocryptfs.conf access on macOSVal
Unlike the FUSE implementation on Linux, macFUSE doesn't cache the file attributes from the `LOOKUP` call, so it calls `GETATTR` prior to accessing a file. In the case of the `VirtualConfNode` (reverse config file passthrough), this resulted in the default `GETATTR` implementation returning an empty result, ultimately resulting in a "permission denied" error. 14:44:14.095207 rx 3: GETATTR n2 14:44:14.095229 tx 3: OK, {tA=1s {M0100000 SZ=0 L=0 0:0 0 0:8954996 A 0.000000 M 0.000000 C 0.000000}} 14:44:14.099943 rx 4: ACCESS n2 {u=501 g=20 r} 14:44:14.099990 tx 4: 13=permission denied By impementing `Getattr` (from `fs.NodeGetattrer`) on `VirtualConfNode` this solves the issue.
2021-09-10inomap: deterministically set root deviceJakob Unterwurzacher
We used to have "first Translate() wins". This is not deterministic, as the LOOKUP for the root directory does not seem to reach us, so the first user LOOKUP would win, which may be on a mountpoint.
2021-08-23go mod: declare module version v2Jakob Unterwurzacher
Our git version is v2+ for some time now, but go.mod still declared v1. Hopefully making both match makes https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work. All the import paths have been fixed like this: find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%

xfstests generic/523 discovered that we allowed to set xattrs with "/" in the name, but did not allow to read them later. With this change we do not allow to set them in the first place.

We need https://github.com/hanwen/go-fuse/commit/fd7328faf9fdf75709f7ba7df7072aaf4eeb18b3 to fix a crash reported in https://github.com/rfjakob/gocryptfs/issues/430 : 2019/10/30 17:14:16 Unknown opcode 2016 panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x508d38] This patch is only in the v2.x.x branch. Upgrade to v2, as the old API is also supported there. Running git grep hanwen/go-fuse | grep -v hanwen/go-fuse/v2 to check for forgotten references comes back clean.

2019-04-08readpassword: delete CheckTrailingGarbageJakob Unterwurzacher
CheckTrailingGarbage was called even when "-passfile" was used, which is stupid, and causes false positives: https://github.com/rfjakob/gocryptfs/issues/391 (false error "Received trailing garbage after the password" when using -passfile in .bash_profile) Instead of trying to improve the logic to handle that case and make everything even more complicated, delete the function. It is unclear if actually helps in some cases, and it definitely harms as shown by the above bug report.
2019-03-26reverse: don't show gocryptfs.conf if a custom config path was passedJakob Unterwurzacher

2019-03-26reverse mode: support wildcard exclude (--exclude-wildcard)Eduardo M KALINOWSKI
This adds support for gitignore-like wildcards and exclude patters in reverse mode. It (somewhat) fixes #273: no regexp support, but the syntax should be powerful enough to satisfy most needs. Also, since adding a lot of --exclude options can be tedious, it adds the --exclude-from option to read patterns from a file (or files).
2019-01-20Revert "syscallcompat: drop Faccessat AT_SYMLINK_NOFOLLOW helper"Jakob Unterwurzacher
Breaks mounting on MacOS: unix.Faccessat on Darwin does NOT (yet) support AT_SYMLINK_NOFOLLOW. See d44fe89ba4f3252c5bd00c4f7730197732f2a26a . This reverts commit 0805a63df1b5f915b228727f6074c2506922d0ad.
